Hodgkin lymphoma presenting as multiple cavitary pulmonary nodules with associated mediastinal adenopathy and neck mass.

Hodgkin lymphoma involving the lung may present in a variety of radiographic and clinical patterns including solid or necrotizing lesions, with or without associated mediastinal adenopathy. Cavitary pulmonary lesions are exceedingly rare, occurring in less than 1% of cases, and are typically solitary. We report a case of an 18-year-old male presenting with multiple cavitating pulmonary nodules and a palpable mass in the neck. Imaging revealed associated mediastinal and cervical adenopathy. Biopsy of the neck mass and lung nodule initially revealed necrosis and granulomata, suggesting infection. Treatment for a presumed infectious etiology was without resolution. Subsequent open lung biopsy revealed marked granulomatous inflammation with diagnostic Reed-Sternberg cells. Hodgkin lymphoma should always be considered in the differential diagnosis of cavitary pulmonary lesions, especially those refractory to treatment.
